According to police, the man contacted two online sex workers and requested they come to an apartment in the West End last week.
When the women entered the suite, the suspect reportedly confined them and then brutally sexually assaulted them.
The two 30-year-old women eventually escaped and called police, but the suspect had already fled when police arrived.
Sgt. Randy Fincham said the suspect was arrested around 8 p.m. PT. on Tuesday.
